Be it known that I, HERBERT J. BREEZE, citizen of the United States, residing at Portland, in the county of lVlultnomah and State of @regon, have invented new and useful Improvements in Tirel illing Compounds, of which the following is a speci fication.

My invention relates to tire-filling compounds, and consists in a compound made up of the following ingredients, combined in the proportions stated, viz:

Glue "One pound. Syrup Two pounds. Glycerin (fine-half ounce. Rosin -One-half ounce. Beeswax One-halt ounce.

it bwomes a solid body possessed of elasticity or springiness and adapted to retain such quality until the tire casing is com-- pletely worn out. From this it follows that the filled tire will retain its shape under all conditions and Will he possessed of the same resiliency and cushioning capacity as a tire filled with air under pressure; also, that punctures of the tire casing will not detract from the springiness of or otherwise affect the tire, and that when the tire is filled with Specification of Letters Patent,

the compound the necessity of pumping up the tire at intervals is done away with.

The practical advantag as of my novel tire will be better appreciated when it is stated that. the glue and syrup form the main solid body, the glycerin prevents the compound from adhering, to the inner side oi": the tire casing, and the rosin and beeswax serve to temper the compound and to prevent shrinkingthereof.

lhe glycerin in the comparatively small proportion. state l-namely, one-half ounce serves to efliciently perform the function ascribed to it without interfering with the solidity of the main body of glue and syrup, and this is true also of the comparatively small proportions of rosin and beeswax. it would also say that experience has Cl6I21011- strated that the composition. composed of two parts of syrup to one part of glue, together with the comparatively small proportions of glycerin, resin and beeswax, is adapted to retain its elasticity or springi ness for an indefinite period, and that therefore the composition forms no etlicient and otherwise desirable filler for tires.

Having described 1n invention, What I. claim and desire to secure by Letters-Patout, is:

The herein described compound consisting of a cooked mixture of one pound oi glue, two pounds of syrup, and glycerin, rosin, and beeswax, in the .)roportions of one-half ounce, each.
